I p This invention has been devised to p r0 vide an improved feeding ord1str1but1ng tubeof that type employed in machines for.

drilling and sowin I seed such as wheat, 6 barley,.maize and ot er gran,or other seed which may be required'to be planted. The

seed may be sown with or without a ferti- :lizing mixture. .Theinvention is particularly useful in sowing wheat and W111 be so c 10describedherein, but it is to be understood that' the invention is n0tlimited/thereto I but as before stated may be used for sowingotherseedsor the like. I I I One of the objects of this invention 1s to.1 provide apparatus capable of being adjusted to enable the distanceknown as the clear- I lance between thesowing rowsor drills to beregulatedor adjusted, i. e. reduced'or increased as desired. in theformer instance permitting a morecompact or close crop to be rown withina given area or acerage than 5 I p b gun-ed tothe machlne w1ll belessened, and

I at1prese'nt, and by doin so largely increasing the yield of grainthereof, andqfurther the density of the crop so' produced greatly5'-"disc(" u'rages the development of weeds and vother rubbish, in mostinstances'preventingl the growth thereof'with the result that a full,idevelopmentis allowed of the grain during its growing, thusconsiderably enhancing the value of the grain when harvested. 5Anotherobj'ect of'this nv'ent on is to pro- 1 vide apparatusto ensureduring drilling and lsowing operations regularlty and certainty of Idistribution of the wheatand accuracy of Isowing thereof. Another ob ectof the inventionflisto provide apparatus to permit simultaneous feedingfrom the onechstrrbuting point of the wheat and; fertilizer to twoorwmorelhoes,discs orad acent to two or 40 more types of a'cnltivator.z-wWith-the present machines of 'thiselass of drill orcultivatorprovision is made for I the employment of acertain number ofsowing--hoes,1 and-it is not possible to addto their number to of themachine. c I

' In thisinvention a machine of correspond:

ing dimensions and the same numberof individual feed' apparatus wlllbeemployed,-

but additional hoes are used and arranged ,infa manner as hereinafterdescribed, to en- 5 able amaximum working efiiclen'cy to be obtained i.e. a machlne constructed according c to the 'fpresent arrangement ofparts which permit increased eifioiency "will sow, say onehundred acresofland Ill within a certain period. willbe able to sow duce the zigzageffect so essential in pre venting the accumulation of rubbish on thehose, such effect however, is not possible with the present small typeof machine em- .ploying one row of hose, resulting in both inconvenienceand delay occurring in clearing away such rubbish.

It W111 be seen fromthe above advantages, a machme embracing my-lnvention 1s'ca pable of performing a large amount of work I and can beplaced on the market at a much lower cost that the present machine inuse,

and further the amount of attentionre the power to carry outthenecessary series of operations performed by the machinewill i powerrequired for propelling the machine,

making it possible to employ less horse or other power, and in theformer instance allow longer working hours.

In order that my invention may be th more fcasily understood, referencewill be made to the accompanying sheet of drawings in whichculturaldrill with" a detachable conduit including a mam conduit section, branchsections and terminal sections, said conduit feeding hoes as hereinafterdescribed f Figure 2 is a front sectional elevation of the structureshown by F1gure1, -port1ons being shown in section online 2 2'of Figure1.

Figure '1 illustrates a side elevationof a portion of the feedingmechanism of an agri- Figure 3 illustrates, drawn to a small scale,

a detachable main conduit section with a two-branch construction ofbranch conduit sections. 4 1 1 I Figure l is a section on line HotFigure 1, and shows a division main conduit section.

Figure 5 shows diagrammatically. the relative positions of the feedingmechanism, the

plate within the lioes and the branched conduit, when a twobranchconduit is used.

Figure 6 illustrates the manner of connecting an adjustable terminalconduit section ofmetal to a branch conduit section.

Figure? is a sectional view, showing the manner of attaching a flexibleterminal conmost suitable, and the invention will be so described andillustrated. Each of the said branch sections 4 and 5 is integral with,or fixed to the main section 3, but each may be connected, or fixed tothe main section in a manner to permit adjustment. Whicheverconstruction isemployed, they will rest'at the required angle orincline, to permitthe engagement of adjustable terminal sections 6'therewith; Each terminal section may be a length of rubber tubing,engaged with a helical thread '6 on a branch section, as shown by Figure7 If metal terminalsections are employed, they may be engaged withthe'branch sections in such manner as to be' free to slip endwiseon thelatter, to a limited extent.

Figure 6 shows suitablemeans for engag- 1 ing a metal terminal sectionwith a branch section. The. sections are arranged to perm1t a freedownward run for the gram -on 'itsway to hoes 7, communicating with thelower ends of the terminal sections 6. Said hoes are provided withsockets 7 loosely receiving the lower ends of the terminal section 6.The hoes are movably connected with the frame of the machine by theusual or any suitablemeans, which may include links 71 pivoted to earson thehoes.

It is to be understood that I do not confine myself to any particularangle or incline of the branch sections 4 and 5, and of the terminalsections 6.

Whatever the arrangement of the conduit sections may be, it is desirablethat they permit the material to flow evenly and with certainty to thedischarge point, i. e. to the mouth of the hoe 7.

- The sections 4 and '5 may be of any desired length, and if desired,more than two branch sections maybe employed, in which case thearrangement will be such as stated before, to allow the material tofreely flow and be delivered to the hoe.

Figure 5 illustrates diagrammatically the relative positions of aplurality of feed mechanisms, designated by the reference letter A, andarranged in a row, and hoes 7 arranged diagonally, the dotted linesindicating approximately the angle or incline at which the branchconduit sections 4 and 5 and the adjustable terminal sections 6 attachedthereto are disposed.

If it is desired, the chute 1, and the main or conduit section 3, mayhave an internal The division plate subdivides the chute 1 and the mainconduit section 3 into two passages 14 and 15 (Figure 4), eachcommunicating with a branch conduit section.

The solid disc of the feed wheel 10, in .some instances isformedcentrally within the rim 9 of such wheel, toensure an even and accuratedistribution of the grain or other material to the passages 14 and 15. i

It will be understood that I may make the size of theopenings 11 and 12according t requirements. 7

To provide, when the division plate is employed in the manner abovestated, the necessary width or clearance of the passage way* at thejointings 0f the main section 3 and'branch sections 4 and 5, I reducethe 1 and a peripheral rim that projects an equal" distance laterally inopposite directions from said web, a delivery chute into which saidwheel projects; the aperture in the wall of said chute'through which thewheel passes having portions ofequal dimensions at both sides ofsaid'web, a conduit connected to and extending downward from thedelivery chute and having two terminal branches, and a removablepartition extending through said conduit and into the delivery chute toprovide separated passages from the feed wheel to the inlets to saidbranches of the conduit; V

2. In a machine for continuously sowing seed, the combination of afeeding wheel mounted to rotate about a substantially horizontal axisand having a central disc or web and a peripheral rim that projects anequal distancelaterally in opposite directions from said Web, a deliverychute into which saith Wheel projects, the aperture in the wallet saidchute through which the whee] passes having'portions of equal dimensionsat both sides of said web, a conduit eouneeted to and extending downwardfrom the delivery chute I and having two terminalb1'2u1ehes, 'and aremovable partition extending through said eonduit'and into the deliverychute to points above the horizontal plane of the lowest portion of therim of the feed Wheel and above the level of the feed openings in thedelivery chute, for the purpose described.

In testimony whereof I have signed my name tothis specification.
